Are odorant-binding proteins involved in odorant discrimination?
Pheromone-sensitive sensilla trichodea of nine moth species belonging to six families and three superfamilies of Lepidoptera were immunolabelled with an antiserum against the pheromone-binding protein of Antheraea polyphemus. Strong immunolabelling of the sensillum lymph was observed in all long sensilla trichodea of A. polyphemus, A. pernyi (Saturniidae), Bombyx mori (Bombycidae) and Manduca s...
متن کاملNatural variation in odorant recognition among odorant-binding proteins in Drosophila melanogaster.
Chemical recognition is essential for survival and reproduction. Adaptive evolution has resulted in diverse chemoreceptor families, in which polymorphisms contribute to individual variation in chemosensation. To gain insights into the genetic determinants of individual variation in odorant recognition, we measured olfactory responses to two structurally similar odorants in a population of wild-...
متن کاملDiversity of odorant-binding proteins and chemosensory proteins in insects.
Odour and pheromone perception occurs through a complex series of events, many aspects of which have been elucidated in the most recent years. The discovery of membrane-bound olfactory receptors, both in vertebrates and in insects, and their functional expression in heterologous systems have shown that they can be directly activated by odorant and pheromone molecules. Although a pathway of sign...
متن کاملImmunolocalization of odorant-binding proteins in noctuid moths (Insecta, Lepidoptera).
Odorant-binding proteins were studied in the noctuid moths Agrotis segetum, Autographa gamma, Helicoverpa armigera, Heliothis virescens and Spodoptera littoralis using antisera raised against the pheromone-binding protein (PBP) and general odorant-binding protein 2 (GOBP2) of Antheraea polyphemus (Saturniidae). Proteins immunoreacting with these antisera were only found on the antennae and PBP ...
متن کاملCharacterisation of Bombyx mori Odorant-binding proteins reveals that a general odorant-binding protein discriminates between sex pheromone components.
In many insect species, odorant-binding proteins (OBPs) are thought to be responsible for the transport of pheromones and other semiochemicals across the sensillum lymph to the olfactory receptors (ORs) within the antennal sensilla. In the silkworm Bombyx mori, the OBPs are subdivided into three main subfamilies; pheromone-binding proteins (PBPs), general odorant-binding proteins (GOBPs) and an...
